Katanax

X-300 fluxer

Compact fusion system for medium-sized laboratories, fusion of concentrates and difficult-to-digest environmental samples with three simultaneous crucibles.

• fusion
• Metallurgy & smelting
• Environmental labs

• Sulphide concentrates for XRF analysis
• Soil and sediment digestion for total measurement
• Slag from the recycling industry
• Geochemical samples at commercial analytical labs

Crucibles	Pt/Au or graphite
Operating temperature	15 – 30 °C

The X-300 is an electrically powered fluxer that doesn't require gas installation, making it ideal for labs where gas safety is complicated. Three simultaneous crucibles provide good capacity without requiring large-scale lab space.

Lithium borate flux in an inert atmosphere provides complete homogenisation of sulphides, oxides, and refractory samples. Program control ensures reproducibility and full documentation of each fusion.

Fusion digestion requires reliable crucibles, moulds and precisely controlled induction — otherwise the entire XRF workflow is affected. Our Katanax technicians service the fusion system so daily operation and sample repeatability hold across shifts.

• Annual check of induction, temperature profile and motion axes with documented protocol.
• Stocked platinum and graphite crucibles, casting moulds and lithium-based flux in the Nordics.
• Preventive replacement of wear parts (lift arms, sensors, heat shields) before failure.
